“…The suspension consists of three cavities: I ~ III. The cavity I and cavity II are filled with oil, cavity III (energy accumulator) consists of two parts, the lower is the oil, the upper is the inert gas, the gas and oil are separated by an airbag, which can prevent the inert gas dissolving into the oil at high temperature and high pressure, the inert gas acts as an elastic element [20].…”

“…Finally, the effective stiffness of the suspension increases and the damping decreases. S. Francois van der Westhuizen et al [14,15] compared different gas models to calculate the spring force of the hydro-pneumatic suspension. This study compares the performance of three ideal gases (IG) with the energy equation, Benedict Webb Rubin (BWR) equation with and without the energy equation (EE).…”

A mine dump truck is exposed to heavy load and harsh working environment. When the truck passes over the road bumps, it will cause the body to tilt and the tires to "jump off the ground" (JOTG), which will affect the stability and safety of the truck, and will cause impact damage to the body and suspension system. To avoid this situation, a kind of Novel Single-side Coupling Hydro-pneumatic Suspension (NSCHs) is presented. NSCHs consists of two cylinders in parallel, which are connected to the accumulator by rubber pipes and mounted on the same side of the dump truck. Theoretical analysis and experimental research were respectively carried out under the road and loading experimental condition. The experimental results show that compared to the conventional single cylinder hydro-pneumatic suspension, under the loading experiment condition, the maximum overshoot pressure of the NSCHs was reduced by 0.4 MPa and the impact oscillation time was shortened by 4.13 s, which plays the effective role in reducing vibration and absorbing energy. Further, it is found that the two cylinders are coupled during the working process, and the NSCHs system can achieve uniform loading and displacement compensation, thus the novel dump truck can avoid the occurrence of the JOTG phenomenon.

“…This new type of hydro-pneumatic ISD suspension is in principle equivalent to the mechanical two-stage ISD suspension, 15–18 and is therefore easy to equip on vehicles. Based on AMESim, 19 a 1/4 hydro-pneumatic ISD suspension is constructed for parameters optimization, 20,21 and a whole vehicle model is established for performance simulation. Finally, a road test 22 verifies that the hydro-pneumatic ISD suspension can improve the comprehensive performance of heavy multi-axle vehicles, effectively suppressing the vibrations of vehicle sprung and unsprung mass, while improving the ride comfort and road friendliness.…”

Aiming to improve the road friendliness so as to reduce the road damage caused by heavy multi-axle vehicles, and to enhance the ride comfort, we propose a kind of hydro-pneumatic ISD suspension structure, which is equivalent to a two-stage ISD structure integrating a traditional hydro-pneumatic suspension and a fluid inerter. Firstly, based on the 1/4 model, a genetic algorithm is used to optimize the key structural parameters of hydro-pneumatic ISD suspension. Secondly, the AMESim dynamic model of heavy multi-axle vehicles is built for the performance comparison between the traditional hydraulic and hydro-pneumatic ISD suspensions. Finally, this paper machines a hydro-pneumatic ISD suspension to replace the traditional hydraulic one in a heavy multi-axle vehicle to carry out a road test. Test results indicate that the proposed suspension can effectively restrain the vibrations of sprung and unsprung mass and improve ride comfort as well as road friendliness. The hydro-pneumatic ISD suspension can be applied to engineering.
